The decades-lasting British science fiction series Doctor Who originally aired on PBS in America during the 1970s and was noted for both its cleverness and its low production values. Cybermen -- The Early Years covers the beginnings of the Cybermen who would evolve from their cold-hearted roots -- after their discovery in the arctic by the series-leading doctor -- into definitive recurring enemies on the program. Commentary by Colin Baker (the sixth actor to play the doctor on the show) incorporates footage from several episodes, as well as four episodes in their entireties: episodes two and four of The Moonbase and episodes three and six of The Wheel in Space. ~ Sarah Sloboda, Rovi
